MOLD-BOARD FOR bLows.

c SPECIFICATION forming part of Letters Patent No. 355,933, dated January 11, 1887.

` Application tiled September 9, 1886. Serial No. 213,138. (No model.)

following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and Yto letters or gures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in plows; and it consists more especially in the construction of a moldboard and the attachment thereof to the share and plow-frame.

My invention also consists in the construction and combination of the parts,fas shown in the drawings, and as will be hereinafter fully set forth.

In the accompanying drawings, which illustrate my invention, Figure l is a perspective view of a plow constructed in accordance with my improvement. Fig. 2 is a bottom view. Fig. 3 is a side view of the plow, looking toward the landside. Fig. 4 is a vertical sectional view. Fig. 5 is a detail perspective view of one of the braces, aud Fig. 6 is a detail perspective view.

Arefers to the plow-beam,\vhich is bifurcated atits rear end, asshown ata, so that oneof the handles, b,will pass through the said bifurcated portion of the plow-beam, where it is attached thereto by a bolt, a. The opposite handle, b', is similar in construction to the handle b, said handles being of equal length. These handles b and b are connected together by transverse brace-rods in the usual manner.

To the beam A in front of the handles is attached a standard, B, which is provided at its upper portion with a plate, c, which has perforations through which pass bolts for securing the standard to the plow-beam, the front or forward bolt also serving to secure in place one end of abrace-bar, c', which extends therefrom to near the upper end of the handle -b. The lower end of the standard is bent at an angle, as shown at d, so thatit will lie over ble bolt, which assists in holding in place the landside proper and the lower end of a curved metallic bar which is attached to the lower end of the handle b, said bar being referred to by the reference-letter e.

E refers to a metallic casting, which isrnade up of a single piece, the contour of the front portion, D', being the same as the contour or configuration of the share and lower portion of the mold-board of the plow, and the longitudinal bar, D, hereinbefore referred to, -is formed integral therewith, said casting E forming substantially the main frame of the plow. To the front portion, D', of the casting E is attached by suitable bolts the share F, which is provided in rear of the point of the plow with an upwardly and rearwardly projecting colter, f.

, Instead of providing the plow with a solid mold-board I make use of what I term moldboard strips,7 said strips being indicated by the letters G, H, and I, which are curved, as shown in the accompanying drawings, the lower ends thereof being attached by suitable bolts or rivets to the upper edge of the portion D of the casting E.

The mold-board strip Gis curved upwardly and rearwardly, and is secured by means of a bolt, g', vto an angle-brace, g, which is attached to the standard B, and its rear end is reduced in size and bent inwardly,so as to engage with a perforation in the bar e', which is attached to the lower end of the handle b', said barbeing connected at its lower end to a brace, as shown in Fig. 5. rIhe mold-board strip H' is also curved upwardly and rearwardly, but to a less extent than the adjacent strip above,and it is also braced to the standard B by a bar,h. The end strip has two projecting portions which extend under the share F, the upper projecting portion being braced by contacting with the upwardly-projecting portion i of the brace shown in Fig. 5. The brace shown in Fig 5, hereinbefore referred to, is secured at one end to the bar D of the casting E, and at its opposite end to the rear portion of the por- IOO tion D', and to its intermediate portion this brace J has attached thereto the end of the bar E. rlhe landside K ofthe plow is of ordinary construction.

A plow constructed as hereinbefore described is especially adapted for stirring the What I claim as new, and desire to secure by Letters Patent, is-

In a plow, a skeleton mold-board comprising a strip, G, having a lower arm to abut upon the share,and curved upwardly and rearwardly to the handle-brace, a central strip, I-I, anda forked end strip, I, arranged t0 complete the share-extension and secured to the arched brace J, substantially as shown, and for the purpose set forth.

In testimony whereof Iaiiix my signature in Vpresence of two witnesses.
